Also called: acetylsalicylic acid, asa
What it is used for
In higher doses it relieves pain and fever; in low doses (75 to 150 mg) it helps prevent heart attacks and strokes.
How it works
At pain-relief doses it blocks prostaglandins; at low doses it permanently stops platelets from sticking together, which is why 75 to 150 mg a day helps prevent clots in people with heart disease.
How to take it
Low-dose aspirin is taken once a day after food, exactly as your doctor prescribed; do not stop suddenly without advice. For pain, adults take 300 to 600 mg every 4 to 6 hours after food, up to 4 g a day.

Be careful
Can cause stomach bleeding. Not for children or teenagers with fever (risk of Reye's syndrome).
Other medicines and interactions
Raises bleeding risk with warfarin, clopidogrel, ticagrelor, NSAIDs and SSRIs. Ibuprofen taken just before low-dose aspirin can block its heart-protecting effect. Raises methotrexate levels.
Pregnancy and breastfeeding
Low-dose aspirin is sometimes prescribed in pregnancy (for example to prevent pre-eclampsia); otherwise avoid pain-relief doses, especially in the last three months. Avoid regular use while breastfeeding unless a doctor prescribes it.
